She may play a depressed teenage girl on the hit series, 13 Reasons Why, but Katherine Langford looked nothing like her character on Tuesday as she strutted to Jimmy Kimmel Live in L.A. Read on to see the pics!

Though she stars as Hannah, a high school student, on the show, Katherine is actually 22 years old.

Since debuting the second season of the series on Netflix a few weeks ago, Katherine was quick to let go of the backpacks and jeans Hannah always wears in favor of her more age-appropriate style—a sharp white suit paired with an awesome David Bowie T-shirt.

She completed the mature look with a pair of fabulous shades and pointy pumps. She also styled her long brown hair in sexy waves.

And literally that very same day, she was snapped in a totally different but equally fierce outfit—green plaid pants, black pumps, a black long-sleeved shirt, gold bracelets, and a bold red lip.

Now that Katherine has been donning this grown-up look, does that mean she’s not returning a Hannah on the show, which was just renewed for a third season? The jury is still out on that (though they begin shooting later this year). Last month, she wrote a cryptic message on her Instagram saluting Hannah, who commits suicide and is mostly shown in flashbacks, including the words, “This show will always be a special part of my life, and regardless of whether Hannah is there or not.”
